This invention relates to new and useful improvements 1n speedregul'ating devlces for feeding attachments for thrashing ma-' chines and has for one of its objects to pro vide manually controlled mechanism whereby the feeding attachment may be driven at two speeds and also capable of being shifted to a neutral or inoperative position to render the feeding attachment inoperative while the remaining thrashing machine structure is in operation.

In thrashing machines, there is a device that carries or feeds the bundles or sheaves into the separator and the present invention is designed to cause the bundle feeder to operate at two different speeds or to remain out of operation whenever desirous.

' With the above and other objects in view that will become apparent as the nature of the invention is better understood, the same consists of the novel form, combination and arrangement of parts hereinafter more fully described'shown in the accompanying draw ing and claimed.

In the accompanying drawing, wherein like reference characters designate corref sponding parts throughout the several views,

Fig. 1 is a side elevational view of a part of a thrashing machine equipped with the.

of the present invention,

Fig. 2 is a side elevational view speed changing device removed from the thrashing machine, 4

Fig. 3 is an enlarged side elevational View of the device, with a part of the wall broken away to show the chain and sprocket drive mechanism, 1

Fig. i is an edge elevational view of the speed changing mechanism, and

Fig. 5 is a longitudinal sectional view showing the drive shaft of the. thrashing machine and the gear and clutch mechanism associated therewith.

As shown in Fig. 1 the casing 1 has the drive shaft 2 extended laterally therefrom while the reference numeral 3 designatest-he carrier driven shaft. The invention being designed for varying the speed of rotation of the carrier driven shaft 3, there is pro- .videdchain and sprocket mechanism with a clutch connection interposed between the driving shaft 2 and carrier driven shaft 3.

The mechanism for procuring the variance in speed of rotation of the carrier shaft 3 is I .carriedby a supporting structure comprising a metallic 'plate' carrying laterally directed bracket arms 5 and '6 adjacent the upperand lower ends thereof thatsupport at their time outer ends a wooden bar 7. The drive shaft" i 2 extends through the plate 4 and is. jour-[ above the .driveshaft 2 ,while the other end of'the counter shaft 8 is journaled in the wooden block 9, the wooden bearings for the shaft becoming saturated with oil and eliminating the'necessity of frequently 111-" bricating the same.

A relatively large sprocket wheel 1O isfixed to the end of the carrier. driven shaft 3 within the supporting structure 'while a relatively small sprocket wheel 11 is fixed to the end of the counter shaft 8 in tracking alinementwith the sprocket wheel 10, a loose sprocket wheel 12 being freely journaled upon the drive shaft 2 and over all-of which sprocketwheels, asp'rocket chain 13 passes. The sprocketwheel 12 is retained against sliding movement upon the drive shaft 2 but is permitted to freely rotate thereon'and as shown in Fig. 4 the sprocket 12 is carried by a hub bearing having a clutch face 14 upon one end thereof; 7

As shown in Fig. 5 the drive shaft 2 journaled in the bearing 15 in the metallic plate 4 is keyed as at 16 within one end of the tubular shaftl? with the other end of the tubular shaft journaled in the wooden bar 7. The end of the tubular shaft '17 opposite the sprocket wheel 12 has a sprocket wheel 18 freely rotatable thereon and retained against sliding movement and with a clutch face 19 uponone end thereof as shown in Fig. 4, the sprocket wheel 18 being alined with the relatively large sprocket wheel-20 upon the end of the counter shaft 8 opposite the sprocket wheel 11, the sprocket Wheel 20 being fixed to the counter shaft. A sprocket chain 21 passes over the alined sprocket wheels 18 and 20..

7 A clutch sleeve 22 is splined as at 23 upon the tubular shaft 17 as shown in Fig. 5 and has clutch faces 14L and 19 that are adapted to engage the clutch faces l i and 19 carried by the sprocket wheels 12 and 18, the clutch sleeve 22 being slidable upon the tubular shaftlr' and keyed thereto for rotation with the shaft. The shifting means for the clutch sleeve 22 includes a lever 2% extending upwardly as at 25 with the lowerend thereof pivoted as ,at 26 to the bracket arm 6, the lever24; carrying a fork 27 extending into the annular race 28 of said sleeve to permit free rotation of the clutch sleeve and also effect sliding movement thereof upon the tubular shaft 17. The clutch sleeve 22 may be, operated from the upper side. of the thrashing machine with either of the clutch faces 14-14%01' 1S)19 brought into play.

. Itis also intended that the clutch sleeve be .the carrier driven shaft 3 at its greatest speed When the clutch sleeve 22 is shifted in the :opposite direction to cause the clutch faces 19 and 19 to belengaged, the sprocket Wheel1-8 being keyed to the tubularshaftl'? operates the larger sprocket, Wheel 20 upon .the counter shaft 8 at a lower speed. When theclutchsleeve 221s in the neutral position SllOWIIlIl ,Fig. v4;, the carrier driven shaft 3 is out of operation While the drive shaft 2 continues to operate theremaining mechanism of the thrashing machine.

From the above detailed description of the invention, it is believed that the construction and operation thereof will at once he appar- I ent, and while there ishereinr shown and described the preferred embodiment of the present invention, it is, nevertheless to be understood that minor-changes may be made therein Without departing from the spirit andscope of the invention as claimed.

VVhatis claimed is V v I 1; In a feeder for thrashing machines, the combination'with the drive and'carrierdriven shafts, of a counter shaft, a relatively ,smallsprocket wheel fixed to the counter shaft, a sprocket Wheel on the drive shaft, a sprocket chain inclosing the sprocket wheels, 'thesprocket Wheel on the drive shaft being freely rotatable, a manually operable clutch for lockingthe same to the drive shaft, a relatively large sprocketwheel fixed to the counter shaft, a second sprocket.
